Normally S3 methods such as as.ts.zoo are not exported unless there is particular reason to access them directly. Rather one accesses them via their generic which dispatches the appropriate method based on the class of its first argument. That is if z is a zoo object then as.ts(z) dispatches as.ts.zoo. If you really want to see it you can do this zoo:::as.ts.zoo -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
